To ALL wHoM 1T 'MAY CONGERN:`-

Be it known that we, vANDREWBumm/lu and JOSEPH EvANs,'both of the city of- Newark, in the ounty of Essex, and.Sta.te of New' Jersey, have'invented an improved Scanning Machine for Tinsmiths Use; a'ndwe hereby de'clore the following to be a, clear andv exact description thai-cof, reference being hadftothe annexed drawings', baking apartof this specicltion, in Which- Figure 1 is a'side elevation and' v Figure 2 a, front elevation of the machine. Figure 3 is a. representation of 'the'njanner inv which tnefiock 1s applied to the guide-plate 'preparatory to` V being closed by the die; and v i I .y l

`Figure 4 isa. representtionof the lock after it hes been closed by the die. Corresponding letters ofreference indicate'like parts.

This invention consists in 'the employment of 1e. perpendicular-acting dic',vA, figs. I aud 2, the under side of which is cut out to form such shape of sean; as moy be wanted. This die works in combination with and is guided by a, plate, B, iig. 1, which plate-also acts as a stop or gauge/for the lock, and is afljuistoble with'refrence to its distance from the revolvingvmandrel, C, gel, so as to llow seems of different thcknessesto pass through when closed. The revolving meindrel 4C'ghiig. 1, is inode with oneoj more flat or groovcd surfaces forming the bed of' the die, und' can be used with t or grooired, strazight'orcurveddies, :1s occasion requires. a'D, tig. 1,'-is sliding gauge,'used as a. stop, and'to'keep the ends of the locks even. The die is attachedA to-a rod or bar, E, fig. l-,Worliing in guides F F, and is operated by ineens of the vlever G, andlink-rod H, connectingwith the' fooltfleve'r I. The spring J serres t:e purpose of raising the die when the foot Ais lifted froln the .level-QA Y The manner in which our inventionis used islas follows The locks being st prepared in the usual manner, the opera-tor places one piece on the mandrel by-sliding it-und'er 'the guide-plate, the edgeof the lock being up he then hooks on nother piece and draws the lock close against the guide-pleite, asvshown in iig'. 3, being careful thaty the ends touch the sliding gauge; he vthen causes' the die to descend smartly by ineens of the foot-lever,

which closes the lock, es shown in fig. 4 the foot is then raised from the lever and the die recedes from the seem,

which is now capable of being drawn under'theguide-plate- Anotherpiece is thonhookcd on and the operation continued until the work is completed." Whnt we consider of advantage in our invention is, that-with it'seaims can be formed at one operaition, milking it unnecessary afterwards to flotten the seam by rnhllet, endit is scarcelyV possible with it to make a false-seam, as is so often the casewith the machin-es now iniuse. We' do vnot restrict ourselves to the particular form of theumachine'as' shown in `the drawings, nor to they particular shape of the die face as thereexhibited'; the same being made of dxerent shapes,uccordingtdv the class of seams required, being either lint, grooved, straight, or curved, as the casemayfbe', when used with a corresponding matchfbed in the revolving mndrel. v v v Whatwe claim as our invention, and desire to secure by`Letters' Patent, is!- 1 The die A, figs. -1 and 2, in combination with the guide-plate B, figs.' land 2, when constructed-in the nranner and forthe purposes set forth. Y 'I 2.
